House lawmakers aggressively questioned Zuckerberg Wednesday on user data, privacy settings and whether the company is biased against conservatives.
Facebook founder Mark Zuckerberg has admitted that his personal data was handed over to election consultants Cambridge Analytica, the British firm accused of helping politicians use Facebook data to manipulate users' voting intentions around the world.
If Facebook stopped collecting this data, it would undermine its entire business model.
Clicking on the "Review Now" prompt is created to take you to your settings for Facebook Messenger on mobile - but this didn't work when we tried it. Zuckerberg testified for around five hours in a Senate hearing on Tuesday.
"The most important thing I care about right now is making sure no one interferes in the various 2018 elections around the world", he told a 44-Senator panel.
Some speculated that the 33-year-old social media chief may have requested the seat to appear taller, more authoritative and imposing during the grilling.
"We heard feedback from thousands of parents and they want control over their communication with kids", Zuckerberg said.
But it was too late to stop the mocking on social media. It moved even higher when he started addressing the questions from lawmakers and finished the day with a 4.5 per cent gain.
During the hearing, Zuckerberg fielded a myriad of questions regarding Facebook's data collection views as well as the social media giant's alleged monopoly on its market space.
Facebook CEO Mark Zuckerberg speaks at his company's annual F8 developer conference in San Jose, Calif. Zuckerberg wrote in a Facebook post on May 21, 2017, that he's not running for public office. For most of our existence, we focused on all of the good that connecting people can do.
In the wake of the massive leak of user information to Cambridge Analytica, which worked for Donald Trump's 2016 campaign, Zuckerberg reiterated that the company had shut down the pipeline that allowed data - including his own - to slip without consent into the hands of third parties. He asked Zuckerberg if content on Facebook is filtered, and who determines what is appropriate and inappropriate for the site. "In order to do that we believe we need to offer a service everyone can afford, and we're committed to doing that". He did not name specific companies. Earlier this year, special counsel Robert Mueller charged 13 Russian individuals and three Russian companies in a plot to interfere in the 2016 presidential election through a social media propaganda effort that included online ad purchases using US aliases and politicking on USA soil.
U.S. Rep. David B. McKinley told Facebook CEO Mark Zuckerberg he and Facebook were "hurting people" with its failure to quickly remove ads on the site that push illegal opioids. We build enterprise software, although I don't consider us an enterprise software company.
Asked if his employees had been interviewed, he again responded yes but added: "I have not", CNN reported.
"Our work with the special counsel is confidential".
Whilst being grilled by Senator Orrin Hatch, Zuckerberg was asked whether Facebook would always be free.
"I don't want anyone at our company to make any decisions based on the political ideology of the content". But after two days of congressional testimony, what seemed clear was how little Congress seems to know about Facebook, much less what to do about it.
Facebook introduced Messenger Kids - which it says is its first app for kids - in December, and expanded the app to Android in February.
This makes a hard blow to the privacy claims made by Facebook.
